This type of error message *usually* means that you haven't set your LD_LIBRARY_PATH to point to the intel library. Further, this *usually* means that you aren't sourcing the iccvars.sh file in your shell startup file on remote nodes (or iccvars.csh, depending on your shell).

Remember that the LD_LIBRARY_PATH has to be set to include the location of the intel libraries on *all* nodes -- and since mpirun launches on remote nodes, you need to set this in your shell startup files (e.g., $HOME/.bashrc if you are using bash).
